I’m not using RTPEngine…the upstream proxies are handling all media, NAT traversal, etc. so the OpenSIPS instances can always reach the endpoints. I’m using clusterer module to share the user location and dialogs with different active tags per node. There is zero loss of media on switch-over and sometimes a little longer PDD for new calls during switchover until the upstream proxies detect the instance down. The only part I can’t seem to get to work is handling the final BYE for calls that were on the failed node originally. The re-invite ping will correct end them but would like to be able to fix it completely…but maybe that is not currently possible.
